EWM Update: Color & Monochrome

The emulator now has the option to switch between color and monochrome
support with the --color command line option.

Only green is supported for monochrome, but I plan to support all the
common colors like white, amber and scanline emulation..

Yes, the colors are not right, and there is outstanding work to make
colors look more solid and follow NTSC display rules.

It is still weird for me to see games in colour. I grew up in The
Netherlands, where PAL is used
for colour encoding. The Apple ][+ only supported the North America
NTSC standard, so we could only
use the computer with a green monochrome display.

If you are interested in playing around with my emulator, you can find
the project at github.com/st3fan/ewm.
